# Load Packages-----------------------------------------------------------------
# Using the "pacman" package for managing add-on packages. It will install
# packages, if needed, and then load the packages.

# Install the package manager if not already installed.
if(!("pacman" %in% installed.packages())) install.packages("pacman")

## Make a list of add-on packages for the project
# e1071: offers an interface to the C++ implementation of SVM
# dplyr: data manipulation
# ggplot2: Data visualizations
# RColorBrewer: provides color palettes
# patchwork: helps add ggplot2 plots together to compose multiplot layouts
# knitr: dynamic report generation
# kableExtra: used with knitr::kable() to generate advanced tables
# scales: provides the percent function for adding the percent label
# mice: missing data imputation
# caret: contains functions to streamline the model building process 
# cvAUC: calculates cross-validated area under the ROC curve (AUC) estimates.
# verification:
# pROC: for creating ROC curves
# naniar: missing data visualization
# UpSetR: 
# earth: for fitting Multivariate Adaptive Splines (MARS) models 
# depends on: Formula, plotmo, plotrix, TeachingDemos
